Abstract

The invention provides a lithium battery with total solid ions for conducting power, effectively solving the problems in the prior art that the energy density and the power density are low and the service life is short. The technical scheme is that the lithium battery comprises a positive electrode, a negative electrode and a housing, wherein the positive electrode and the negative electrode are arranged in the housing; a positive pole connected with the positive electrode and a negative pole connected with the negative electrode are respectively arranged on the housing; the positive electrode is a positive plate comprising of aluminum foil and nanocarbon/sulphate composite material coated thick in 2 to 10 microns on the aluminum coil; and an LiPON solid electrolyte film is arranged between the positive electrode and the negative electrode. The lithium battery has a simple structure, is easy to produce, has a good effect in use, high energy density, high power density, high charging and discharging rate and long service life, and is an innovation based on a power lithium battery and an energy storage battery.

Description

technical field [0001] The invention relates to energy sources, in particular to a lithium battery with all solid ion conduction power. Background technique [0002] Since the commercialization of lithium-ion batteries in the early 1990s, they have developed rapidly due to their superior performance, and have been widely used in many fields such as transportation, mobile communications, notebook computers, and digital electronic products. . However, the electrolyte of lithium-ion batteries mainly used at present mainly contains flammable liquid organic substances, which brings great safety hazards to lithium-ion batteries in use, and limits the continued expansion of its application range to a certain extent. Although the polymer electrolyte alleviates this problem to a certain extent, the polymer electrolyte itself is prone to "dehydration" during use and the electrochemical properties of lithium or other high-potential intercalation materials are unstable. One material i...
